SLIDE 10 WSH is better than standalone systems due to flatter generation pattern, lower tariffs and lower risk exposure to regulatory changes
- Solar radiation is higher during the
day and typically wind blows higher during the night/early morning
- In India, solar and wind also
complement each other seasonally- wind is higher in monsoons, when solar radiation is lower
- Hence, reduces risk of restrictions
imposed by regulatory regime on supply/demand matching. Ex. Currently in Karnataka, power generated in peak time of day bands can only be supplied during peak slots
- Typically WSH can replace 78-80%
- f energy requirements vs. 50-60%
by standalone solar/wind
- some representative graphs of
generation pattern
1
Hybrid plant has a consistent generation pattern as compared to standalone systems
transmission infrastructure for wind and solar and hence costs are lower resulting in a lower farm gate tariff
- Since we use a lower transmission
capacity, transmission charges and losses are lower; lowering landed delivery cost. ~ 15 paise. difference
- Higher PLF of WSH plants translate
to lower per unit cost as compared to other standalone wind/solar systems
- Some state governments are also
coming out with policies which will further encourage hybrid plants and exemption on charges may be applicable
2
Lower landed cost in WSH due to more efficient transmission system and higher PLF
- Greater Savings
- Greater renewable
penetration
